The objectives are:
1. to provide the necessary background in electromagnetics and radiation physics in order to study wave propagation of short wavelengths (<20 mm) in the atmosphere and through optical systems for detection.
2. to provide an understanding of basic optical systems and traditional detectors for passive (photometers, imagers, spectrometers, and interferometers) and active systems (lidar).
3. to understand and implement basic signal processing activities associated with optical remote sensing, including image processing.
4. to understand remote sensing platform traits including ground and spacecraft systems.
5. to have a basic understanding of the atmosphere and measurement parameters including composition, density, temperature, and wind (Doppler) and to experience a real world analysis problems.
